Hi Oswaldo,
Thanks for posting. You have a strong candidacy. To answer your two questions:
1. For your GMAT score, it is important to remember that your highest exam score is self-reported on your application. This means that an admissions team will be focusing on your best score, which is why there is no harm in taking the test again if you feel you can improve your score. If you'd like, we provide free GMAT advice here:

For the entrepreneurial venture, what is most important to an admissions teams is that you outline what your future goals are, and that you have taken steps to put yourself in a position to achieve these goals. If you can show this through your application, then you should not be concerned about pursuing this venture.
If you'd like, we provide free 30 minute phone consultations here:
